Title: 8 channel voltmeter (help) Post by: arash on December 23, 2005, 05:47:13 17:47 Hi.
I was make 8 channel voltmeter (0-5) with diffrent inputs.It works good in proteuse but in real when i connect a voltage to channel 0, it's affect will change the other channels voltage.How can i solve this? Thanks. Title: 8 channel voltmeter (help) Post by: LazBoy on December 23, 2005, 07:17:40 19:17 Use pulldown resistors for stability and against rest cahannel effect.

Put delay routin (50ms) after he selected chanal no..then enable converter (ADC). Title: Re: 8 channel voltmeter (help) Post by: BLK on January 03, 2008, 05:24:11 17:24 check ground path, end reference voltage
Title: Re: 8 channel voltmeter (help) Post by: tenir on January 06, 2008, 12:10:40 12:10 take a lot of measurement and calculate average of them and use delay after selecting channel.

Sorry but please check message posting date. This is obsolete one. Title: Re: 8 channel voltmeter (help) Post by: human_controller on January 17, 2008, 02:03:26 02:03 If u use PIC C ,change this line
#FUSE LVP ==> #FUSE NOLVP #FUSE BROWNOUT ==> #FUSE NOBROWNOUT |
